Step by step
The question
Question: change €50 to pounds, when £1 = €1.16.
1 Write the rate
The rate says: 1 pound is worth 1.16 euros.
From pounds to euros, we multiply by 1.16.
Going back, we divide by 1.16.
2 Divide by the rate
Each £1 gives €1.16.
So we find how many €1.16 fit in €50: we divide by 1.16.
Careful!
From euros back to pounds goes the other way.
We divide, not multiply.
50 divided by 1.16 is about £43.10.
To divide by 1.16, we move the point in both numbers 2 places: 5000 divided by 116.
Money goes to the cent.
So €50 is about £43.10.
3 Check
Let's check: change the answer back.
£43.10 times 1.16 is about €50.
That is what we started with.
So the answer is right!
Let's look back.
First: write the rate.
Then: divide by the rate.
Last: check.
